Refresh Now in dataset not working

All my scheduled refreshes have been working fine.

I have couple of reports where I am manually refreshing by hitting Refresh Now option in the dataset.

When I click it a notification appears for half a second saying that a refresh is happening and disappears, however the refresh does not complete. Usually there would be a loading indicator next to the dataset name - this is also not here.

I am using Premium workspace.

Anyone else having this issue?
